Kristen Stewart doesn't seem like the type who would get all tatted up, but then again, she didn't seem like the type who would cheat on Rob Pattinson with a married man either!

After shooting Sils Maria in Switzerland last week, K. Stew landed at Los Angeles International Airport on Saturday, and she kept her head down but we got a peek at her new ink.

The 23-year-old Twilight starlet debuted her first tattoos back in June -- an infinity sign on her right wrist and four lines on her left wrist -- and in August she showed a large piece on her right forearm. But now it looks like there are even more scribbles on both her left and right wrists ... we're dying to know what it says!
